Answer:
f = 9.25 (I think but maybe I read f(4) wrong)
Step-by-step explanation:
so f(4) means x = 4.
The new equation is
f(4) = 2x4 ^2 - 4 + 9
you first do 2x4^2. The minus 4. The add 9.
the answer to that is 4f = 37
Then solve
F = 9.25
Answer:
yes they are
Step-by-step explanation:
because the metric system is the same
X-int =(-3,0)
Y-int=(0,_1)
Slope: _1/3
When you have a negative exponent, you move it to the other side of the fraction to make the exponent positive.
For example:
or 
or y²
So:

Your answer is B
